To @ZZ whom t may concern Be it known that l, Enntfxn D. Cristi- BELL, residing` at St. Louis. 'lilissourn and heing a citizen ot the United States, have in- Vented certain new and useful improve-- ments in Flexible liletallie Car-Roots, ot' which the following is a ii'ull. clear. and eX- act description, such as will` enable others skilled in the art to which it appertains to make and use the saine, reference heine; had to the accon'ipanying drawings, which illustrattl the preferred forni of the invention, though it is to he understood that the invention is not limited to the exact details of construction shown and deserilied, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In Said drawings Figure l is a fragmentary plan View, showing a portion ot the assembled rooij' for slightly more than onelialt its width. Fig. L). is a transverse sectional View taken through Fil?. l to one side oi the roof cap, and is partly broken away at. the running,r board saddle to show the passage of said cap and its associated parts therethrough. Fig. 3 is an enlarged transverse sectional View of the outer portion of the root that shown at the lett in Fig. 2, hnt is centrally taken, as shown oy line l--3, ot Fig. l. Fig. '-l is a fragmentary plan view 0i the parts shown in Fig. 3, but is broken away at the lett to show the relation of the-parts at the eaves in section, and is taken along line Ll fi of that ligure. 5 is a sectional view talicn transversely of the earline at approximately the Vlongitudinal .median oit the roof. A Fig. G is a perspective view, showing the carline approaching the eaves and lacing adapted to the fascia hoard; and Fig. T .is a like', persq'iective View, 1out showing the completed assemblage of tlie parts constituting the joint et cei'itiguous root' sheets at the carline. l ,My present invention relates to ca roots, and it has for an object the eoi'istruetion of a 'root' which shall he composed oit relatively Yfew and simple parts, which may he either purchased in the open market in a 'torni approximating their iinalv shapes, or he easily manufactured with a minimum ot particular preparation, and assembled without the use of skilled labor.

By virtue oithe above outlined. conditions, stocks of the parts may be kept at division terminals, or other points, along a railroad.,

or of a system oi rail nys, and, when nceessary, repairs he readily made in a short time and hy sach help as is availahle, withoutvreturning the car to a remote point.

l\`o.interlocl ing scams, which seamsiuight he forced. open h v tension on the root' sheets, are employed in the construction hereinaiter described, and the danger of the creation ol' leaks is minimized. the design heine such that any possible scraping otu water hetween the roei sheets and the root caps will he tollowed by an automatic lischarge otxthe water over the eaves, through the troughlilie carline without any oiiportunitv `lor the water to iind its way tothe interior of the car.

A flexibility or the root sheets is nrovided torn so that any subsequent changfc in' the relationoil the car training members wil not atleet the integrity ot' the roof, aal the. portions included in the joints are yieldinely interconnected against separation, suchia-s might or-iiinarily occur after a root' has been 1n service 'tor a consideraoie period.

(in railroads whose clearance diagrams reveal tl e necessity ot' a conservation ot lateral Space, the roei herein disclosed is especially valuhle, as there is no apprcciahle proietttion heyond the sides ot the car ol the root caps and there is no requirement for projecting hoods of any kind. i

ln the draw'ineD it beingA understood that the construction ol5 either side oit' the transverse center ot the ci r is the saine, l indicates the side plates and 2 theI ridge pole, and located lai... :nly 1oetween the latter andk each side plate are the usual purlins 'The sheathing l ot the-car hotly nia-y he either ol the mitside or inside typt-1,' the former hein?,l here shown, though in cars having certain i'orms ot' training, particularly some kinds oi" steel lrzuai'ov, it will he frequently, though not always, ciiesirahlc to use the inside sheathing. plate l shown ataseia hoard or plate 5, which is illustratedV as lapping both the side plate and the sheathing.

Extending across the ear and adapted to be supported by and connected to side plates 1, purlins and ridge pole` Q, are troughiilze earlines (3, which, while not restricted to a given torni, are preferably produced troni a relied bar having the section illustrated in the drawings, which' is a well known Carnegie shape. Qbviously, a pressing may be Secured to the side stance is arched, but may have any othe ap` proved outline. j

Vertical. leg and flanges, 8 and 9, respectively, are diagonally coped oil" at the eaves, and the ends of the horizontal web 7. preterably devoid of said vertical leg and flanges, are shown as extended ove' and bent down parallel with the fascia 5, but in some types of cars may be so bent directly over the side plate. Said flanges 8 and. horizontal web 7 form a water chute or discharge channel in the carline, which channel is continued over the fascia by the down turned ends of the hollow cap plate rib, later described.

Secured, as by rivets, to the horizontal web 7 ot' carline 6, toward the opposite ends thereo't', are means for connecting the carline to the car body, such as connection plates 10,

each ol" which has a downturned flange ttached to the side plate 1, though in oxier types ot cars variously shaped structural pieces or pressings'may be used to better advantage.

Roof sheets 11, provided with flanges 12, which rise vertically to an approximate height ot' the flange 9,forn'1ing movable abutment walls. and are there bent downwardly and diagonally to overlap the flanges l) of the carline, extend preferably trom side to side of the car. Said flanges 12 are cut oll" at the eaves and the remainder of each root` sheet is bent down over the fascia 5 and nailed or otherwise secured thereto, as clearly shown in Figs. if, l and 7.

4In some steel side traifiine, however, said rootl sheets may be directly riveted to a side plate or other incinber.

As seen in Fig. 4, the edges of the parts of each roof-sheet which parallel the downturned portions ot' the horizontal leg 7 of each carline (l, are crimped to conform to the outer corners ot' said leg? and lap said downturned portions of the latter.

Mounted upon the roof sheets 11, so as to extend transversely of thereof and to cover the proximous borders and flanges of adjacent roof sheets and the interposed carline, are rrot' caps lo. lVhere the root sheets 11 are continuous from one ear side to the other, so also are Said roof caps. and they have the saine curvature. or outline as thev roof. y

llach rootI cap comprises a longitudinal inverted channel-shaped housing l-l prol plied.

vided with a centrally located opstanding inverted U-shaped hollow rib 15, adapted to receive the vertical leg 8 of Carlino G, to position said cap, and outwardly extending bottom flanges 1G adapted to lie in intimate formations produced in the framingot' the` car superstructure and due to the vibration of the car body.

There is a decrescence ot housing 14 and the rib 15 at opposite ends ot each root cap 1?, and the outer extremities ot each together with flanges 'lli are bent down over the laseia 5, or'side plate 1, asdelerinined by the type ot car to which the roof :ip- Said turned down ends are secured in any suitable manner to the car body. and, in the drawings. bolts 17 are shown as the fastening means. and they pass through the said down turned portions ot'i'oot caps 13 and carlinesl l, tascia board 5, side plate 1 and connection plate or angle 10, the nuts on said boltsl firmly clamping the parts together. The root sheets are protected at the joints throughout the entire length ot the latter by the root` caps, leakage thereby being entirely guarded against.

.Running boai'd saddles 18, supporting the ruiming board 19 are locatedY at the ridge ot the ar over carlines ll. The under side of the saddles 1S are preferably recessed to fit over the root caps 13. and bolts 20, projecting through the saddles 1S, root caps 13 and the lvertical leg of the cai-line (l secure. said saddles in place.'

Frein the foregoing it is evident that yI have produced a flexible metallic root ot few parts and' of simpleicharacter, and in which some ofsaid parts may be purchased as ordinary stock material approximating their finished form, and the remaining parts be constructed at a relatively slight cost. It is also obvious that the roof may be repaired witliout a return of tlie'carrtopa distant shop, and without trained labor, large shop` tollsor special kits.

What I claim is :4-

y 1. ln a car roof, a` :arlinc of substantially an inverted T cross section and having upstanding flanges at each side tliereo'l, pur

lins secured to and beneath said `earline` root sheets over said purlins and having their edges provided with. vertically extend ing ribs adapted to extend over the edge llanges ot llie carline. in combination with a. housing cap having a central hollow rib,

llt)

portions extending outwardly and downwardly from said rib to cover said carline and the ribs on said rootl sheets, and out- 'said flanges, and a cover cap adapted to house` said carline and the edges of said roof sheets, said cover cap being provided with a hollow ridge extending over the fascia board, said hollow ridge constituting a drip opening to conduct water from said trmlgh.

3. In a ear roof in combination, a carline having upstanding flanges at the edges thereof, a vertically extending leg at substantially the middle of said carline, said leg extending to a greater vertical height than said flanges, said flanges and said vertical leg being coped oliQ at the ends of the carline, the web of said carline being bent downwardly and adapted to be secured through the fascia board to the framing of the car. roof sheets having their edges provided with ridges to extend over and loosely inclose the upstanding flanges of the carline, and a cover cap provided with a hollow ridge to embrace said vertical leg, con

tinuous flanges formed at the edges ot said cover cap and adapted to frictionally engage said roof sheets, said hollow` ridge being extended downwardly over the end of said carline to constitute a drip opening for the troughs formed in the main portion of said carline.

4;. In a car roof in combination, a carline having its edges provided with upstanding flanges, roof sheets having ridges formed on the edges thereof, said ridges being adapted to loosely engage the upstandlng flanges on said cai-line, in combination with a cover cap covering said carline and said ridges and having continuous flanges 'extending l'latwise upon said root' sheets adjacent the edges thereof to rictionally engage said roof sheets and maintain the same in predetermined relation to constitute a roof, and means at the ridge of said roof and at the vertical edges thereof for securing said covercaps in position.

In a car root in combination, carlines having upstanding` flanges at the edges thereoi, a vertically extending leg between said lianges, purlins secured beneath said cai-lines, in combination with rootl sheets having means at the edges thereof to loosely engage said flanges, and a cover cap provided with a hollow ridge extending over said vertical leg and outwardly extending portions covering the edges of said root sheets together with donwnwardly extending portions carrying outwardly extending iianges that 'lrictionally engage said roof sheets to maintain the saine in position upon said purlins.

6. As an article of manufacture, a cover cap for a rooting seam, said cover cap being formed with a continuous upstanding rib in the middle thereof, outwardly extending portions adjacent said rib, downwardly extending walls from said outwardly extending vportions, and edge flanges extending substantially at right angles to said walls.

7. As an articleJ of manufacture, a cover cap for roof seams in railway cars, said cover cap comprising a sheet metal member having outwardly extending flanges, upwardly extending walls, inwardly extending portions, and an upwardly extending rib joining said cover portions.
